That won't wotk because you will be geting a new telnet login prompt and
not your old connection. When you initialize a tcp/ip session the server
will remember your adress and port and allocates a port number on his side
for thi connection. And two applications can't have the same port number -
so you can't do it this way.

If telnet would inherit his File Descriptors to child processes you could
do something like "sz --whatever-parameers &7"
(for fd #7) , but AFAIK no telnet implementation does this.
